Get premium, high resolution news photos at Getty Images Large populations of the dinoflagellate Ceratium hirundinella occur regularly in a small productive lake and their decline during September and October is normally associated with mass encystment. Evidence for the major role of benthic cysts in providing the inoculum for subsequent growth is given from morphological and quantitative studies over two contrasting years of cyst production, 1980 The structure of the freshwater dinoflagellate Ceratium hirundinella is shown in Figure 1. Due to its distinct shape, the genus can be readily identified ( Janse van Vuuren et al. 2006 ).

Some aspects of thecal morphology in Ceratium hirundinella are redescribed by means of scanning electron microscopy. The internal anatomy of the cell has been clearly revealed for the first time in serial sections examined by transmission electron microscopy.

Müller) (Figs.1a & b) is a common and widespread freshwater dinoflagellate. C. hirundinella has been found in numerous man-made impoundments in South Africa The dinoflagellate Ceratium hirundinella is a relatively large, slow-growing phytoplankton characteristically found during late summer in water bodies with a warm, stable epilimnion and low nutrient concentrations (Harris, 1986; Heaney et al., 1988; Reynolds, 1997).

hirundinella in Spanish reservoirs The horizontal distribution of Ceratium hirundinella (MULL.) BERGH was investigated in Lake Erken at ten stations in the summer of 1969. Abundance, total length and number of horns were studied. The conclusion is that the lake contained a horizontally uniform population of the alga. A correlation between form variation and the growth curve of the population was found, which can be explainable Blooms of Ceratium hirundinella (O.

ABSTRACT Cyst formation in Ceratium hirundinella (O. F. Müll.) Bergh was studied by light and electron microscopy, using material from several lakes and reservoirs and also laboratory cultures. Cells preparing to encyst build up large quantities of starch and lipid and at the same time reduce their other cell components.
